Patented Sept. 9, 1941 UNITED STATES nr rice 6 Claims.

My invention relates to newV andv useful improvements in bottle caps and more particularly to a cap` which may be applied to the mouthof a bottle or other receptacle and removed when desired without the use of the usual form ofbottle cap remover or other implement.

The principal object of the invention resides in the provision ofl a cap of the character described including top and bottom portions adapted to be nested so that the cap may be apl plied to the mouth of a bottle or other receptacle asv a unitary structure, the top and bottom portions being connected by a foldableor extensible member adapted to be normally positioned between the top and bottom portionsbut permitting the top portion to be removed from the bottom portion and to then pull the bottom portion from the mouth of the bottle or other receptacle.

Another object of the invention resides in the provision of a cap of the character described including top and bottom portions normally nested so that the cap may be applied to the mouth of a bottle or other receptacle as a unitary structure, the bottom portion being provided in turn` with a weakened portion, and means normally positioned v between the top. and bottom portions for connecting the two portions, said connection adapting the top portion to be removed from the bottom portion and on further manipulation to tear the weakened portion from the bottom portion so 1:

that the bottom portion may beremoved from the mouth of the bottle or other receptacle.`

Still another object of the invention resides in the formation of a cap of the character de-v scribed with top and bottom portions adapted to f be normally nested so that the cap may be applied to the mouth of a bottle or other receptacle as a unitary structure, the bottom portion having a tab out from the top thereof with weakened lines leading from the tab, and a member connected to the top portion and to the tab of' the bottom portion, said connecting member' permitting removal of the top portion from Vthe bottom portion and in a manipulation of the top portion tearing the bottom portion along the weakened lines thereof.

Another object of the invention resides in the. provision of a cap of the character described with nested top and bottom portions, the top land bottom portions being connected by a member normally housed between the portions but adapted to be elongated on removal of the top portion from the bottom portion.

With the above and other objects in View, which will appear as the description proceeds, my invention consists in the novel details of construction, and arrangement of parts, described in the following specification and illustrated in the accompanying drawing, and while I have illustrated and described the preferred embodiments of the invention, a-s they now lappear to me, it will be understood that such changes may be made as will fallA within the scope of ther appended claims.

In the drawing- Fig. 1 is atop pla-n. Fig. 2 is a side elevation. Figi; 3 is a transverse vertical section` Fig. l is a, horizontal sec-tion on the line 4-4 of Fig. 3, looking in the direction of the arrows. Fig. 5 isa transverse verticalY section showing a slightly modified form of the invention; and. Fig. 6 is a horizontal section on the line 6 8- of Fig. 5, look-ing' in the direction of the arrows. As stated in the objects of the invention, the cap comprisesA top and bottom portions adapted to be normally nestedA and in the drawing the top. portion is indicated generally at awhile the bot-v tom portion is indicated'generally'at b. Normally .the portions will Abe nested, 'as shown, so that the cap may be placed upon the mouth of a bottle or other receptacle by the usual well known form of bottle capping machine,

Thev top portiono` includes the top I, having the depending flange f, 'which is slightly tapered, as shown more particularly inFig. 3 of the draw` ing. The bottom portion b includes the topv 3' and depending outwardly flared flange 4, which is corrugated-or fluted'n the usual manner, as shown at 5. A cork disc Gf is. normally inserted into theY bottom portion, asl shown in Fig. 3 of the drawing. The top '3, ofthe bottom portion, is,` formed with: the slit or opening 'l forming the tab 8. Leading from the ends 9 of the opening or slit'lf arethe weakened llines It, formed by perforations or indentation's andthese weakened lines extend horizontallyl across the top 3 and vertically ofthe ange 4:.

.In the form of the invention disclosed'in- Figs. 1` to 4 Vinclusive of the drawing thev top and bottom portions a and b are connected byA a cord or wire il, which is normally folded or wound to be positionedbetween the tops of the members as is disclosed quite clearly in Figs.v Sand 4 of the drawing. The end -2,'of' the cord or wire, extends through an opening i3. intheange 2 of the top member, and is bent, as shown, 'while the cppof site end of the cordor wire isengaged through and connected to-an eye Hl struck from the tab 8. In that form of the invention disclosed in Figs. 1 to 4 inclusive of the drawing when it is desired toy remove the cap from'the mouth of the bottle or other receptacle the operator engages the edge of the flange 2, of the top portion a, and

-k forces the 'same upwardly out of frictionali. l engagement with the bottom portion b and when wire or cord II and when the same becomes taut it will pull on the tab 8 and tear a strip from between the weakened lines I thus releasing the bottom portion from the mouth of the bottle or other receptacle. It' will thus be seen that the cap may be removed by a quick pull and it is not necessary to use a bottle cap remover or other implement such as is now done. The advantages of this will be readily understood for quite often a bottle cap remover or other implement is not available or has been misplaced.

In Figs. and 6 of the drawing I have shown a slightly modified form of the invention in which the top portion is indicated at c and the bottom portion at d. 'Ihe top portion includes the top I5 and depending flange I6. The bottom portion d includes the top I 'l and depending ange I8 which is corrugated or luted in the usual manner. A cork disc I9 is inserted into the bottom portion.

A slit or opening 2U is formed in the top Il of the bottom portion d and extending from the ends 2 I, of the slit or opening, are the weakened lines 22, formed by perforations or indentations. These weakened lines extend horizontally over the top I'I and vertically of the iiange I8. 'Ihe slit or opening forms the tab 23, side edges of which are folded to provide the elongated eyes 24. Received in the elongated eyes 24 are the arms of a substantially C-shaped frame 25. The closed end of a substantially C-shaped frame 26 extends through an opening 21, formed in the flange, of the top member d, and a sleeve 28 is positioned on the horizontal portion of the frame 26 to prevent the same from being withdrawn inwardly through the opening 21. The C-shaped frames and 26 are connected by the C-shaped frames 29, 3l), 3| and 32. Normally these C- shaped frames will be folded into the position shown more particularly in Fig. 6 of the drawing to lie between the tops I5 and II of the portions c and d, respectively.

Normally the portion c is` held in position on the portion d by the friction between the flanges I6 and I8. When thus assembled the cap may be applied to the mouth of the bottle or other recep` tacle by the usual form of capping machine. When it is desired to remove the cap from the mouth of the bottle or other receptacle the operator will engage his nger beneath the bottom edge of the flange I6', of the top portion c and force the same upwardly. This releases the top portion c from the bottom portion d and permits the top portion c to be used as a finger grip. By pulling on the top portion c the connecting frames between the portions will be unfolded into straight line and when the same become taut a continued pull on the top portion c will pull the tab 23, of the bottom portion, upwardly and tear the bottom portion along the weakened lines 22. This will tear a strip from the top Il and from the flange I8 thus releasing the bottom portion from the mouth of the bottle or other receptacle and permitting the same to be removed.

From the above detailed description it will be seen that I have provided a novel form of cap adapted to be removed without the use of a bottle cap remover or other implement. The cap is formed of top and bottom portions and when the top portion is removed a quick pull may be imparted to tear the strip from the bottom portion and permit the same to be released and removed from the mouth of the bottle or other receptacle.

In a cap constructed of the two nested portions, when desired, material of somewhat less weight or thickness may be used than is the case in caps formed of only one portion or thickness.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A cap of the character described including top and bottom members and an extensible chain-like member adapted to be normally folded to lie flat between the top and bottom members, one end of said extensible chain-like member being connected to the top member and the opposite end connected to the bottom member.

2. A cap of the character described vincluding top and bottom portions, the top portion being formed with an opening while the bottom portion is formed with an eye, and an extensible chainlike member normally folded to lie flat and to be housed between the top and bottom portions, one end of said extensible member being passed through the opening in the top portion and connected thereto whereas the opposite end is connected in the eye of the bottom portion.

3. A cap ofthe character described including top and bottom portions, the bottom portion having a cut-out ap and elongated eyes formed on opposed edges, and a chain-like extensible member connecting the top and bottom portions and normally being folded to lie ilat between the top and bottom portions, the extensible member including arm portions received in the elongated eyes formed on the flap of the bottom portion.

4. A cap of the character described including top and bottom portions, the top portion having lan opening therein and the bottom portion having a cut-out flap with elongated eyes formed on opposed edges thereof, and a chain-like extensible member connecting the top and bottom portions and normally folded to lie fiat between the topV and bottom portions, one end of the extensible member extending through the opening in the top portion and held against withdrawal and the opposite end having arm portions received in the elongated eyes of the ap of the bottom portion.

5. A cap of the character described including top and bottom portions, the top portion being formed with an opening while the bottom portion is formed with an eye, and an extensible member normally housed between the top and bottom portions, one end of said extensible member being passed throughthe opening in the top portion andv connected thereto whereas the opposite end is connected in the eye of the bottom portion;

6. A cap of the character described including top and bottom portions, the top portion having an opening therein and-the bottom portion having a cut-out iiap with an eye formed thereon, and an extensible member connecting the rtop and bottom portions and normally housed there-- between, one end of the extensible member extending through the opening in the top portion and connected thereto while the opposite end is 'connected in the eye of the `flap of the bottom portion.
